On the Heights

This is getting worse everytime...

"Keep walking. Now" The voice sounded behind me. I felt the gun pressing harder against my back. I did what that man had told me to. After a few steps, I was in the building.

"Get in the elevator" The man said. I got in and turned back, finally seeing who was that man. He had short black hair and was wearing a black jacket and trousers. He had sunglasses too, so I couldn't see his eyes. 

The man, still aiming at me, entered the elevator and pressed a button. The elevator started to go up. It took half a minute to reach the floor we're going to. The man made me get out. When I entered the room, I flipped. Lots of guitars, basses, violins and musical instruments were hanging on the walls and, at the end of the room, there were some drums and harps. Another man came up and stared at me for a while. He finally made a gesture with his hand.

"We didn't expect you so soon..." The man smiled evily. He looked just like a jazz singer would. "But now you're here-"

"What do you want" I interrupted him. That was a big mistake. The man behind me shot his gun and the bullet went through my leg. I screamed in pain.

"Never interrupt me when Im speaking" The man spoke aggresively. "But now you asked..."

He sat down in an armchair and grabbed one of the guitars of the walls. He played a single chord and then looked up at me again. "You're going to give the concert. Look for another bassist, drummer or whatever, but you must give it"

"Where is David?" I tried to sound brave but I probably seemed scared.

"Oh, I don't really know. Some friend of mine wanted him so well. Any last question?"

"Why do you want me to give the concert?"

The man smiled. "Because nobody will be able to hear the bomb timer with the music so loud" He snapped his fingers and then someone knocked me out.
